Tag:natural=cliff/Archive/Proposal

Original Reasoning
Looking for a way to mark Stannage Edge, Froggat Edge, etc. in the peak district. We also have some proper cliffs on the Isle of Wight that could be marked.
Taking Stannage Edge as the example. It is tagged (edit view) but not yet rendered on the map.

linear ways
This has been around a while so I've added a voting section. natural=cliff is already in the standard map features as a node or an area, but I absolutely agree that it would be most useful as a linear feature. I've been using it like that already. MikeCollinson 09:16, 11 June 2007 (BST)
- Somebody's added to Map Features, including as linear ways, so that voting is passed I guess. -- Harry Wood 14:30, 17 March 2008 (UTC)
Direction of the ways
It would probably make sense to demand that cliff segments be drawn with the cliff-top on one particular side (either the left or the right, as long as it is globally consistent it doesn't matter), as renderers will want to know which way the cliff is facing... Morwen 12:08, 29 March 2007 (BST)
- As soon as we agree on a convention for using this tag, that means, if the top is on the left or right side (as Morwen pointed out), we could start using this. To decide this, let's have a look at coastlines. It sais land on the left side and water on the right side of the way. Land is higher than water, so let's just say top of the cliff on the left side and the bottom on the right side of the way to have this in consistent fashion. Maybe this would also allow natural=coastline;cliff, as we all know that there may be such combinations in nature. This would be impossible if we agreed on the other way round. --Brian Schimmel 13:37, 14 January 2008 (UTC)
- Yep. "top of the cliff on the left side" I'd a agree with that. -- Harry Wood 14:30, 17 March 2008 (UTC)
Other 'cliff' definition questions
Two other things come to my mind:
- To make this tag more useful, I think we should allow to use it not only for natural cliffs, but also for man-made cliffs. Of course we could also introduce man-made=cliff, but in my opinion, make things simple and usable, instead of reaching for 100% correctness in small details -> natural=cliff should be enough.
- Another question arises: Is it important for a cliff that you can see the naked rock, without soil and plants on it, or can a very steep forest floor also qualify as a cliff? In my opinion, every place that is too steep to be walked on should definitely be in a map. If you don't think this can be called a cliff, we really need another tag for this kind of map feature! --Brian Schimmel 13:37, 14 January 2008 (UTC)
- barrier=slope? natural=slope?

- I approve the extension of natural=cliff to include linear ways and also to my own proposals I added recently, if this is possible ;-) --Brian Schimmel 00:12, 17 January 2008 (UTC)
